Project description:The kidney is the main hematopoietic organ in teleost fish. Various stages of hematopoietic cells were observed in the interstitial tissue of the kidney. We recently demonstrated that zebrafish hematopoietic stem cells (HSCs) expressing jam1a were specifically localized along the renal collecting ducts in the adult kidney. Interestingly, most of HSCs invaded into the intracellular spaces of the epithelium in collecting ducts, suggesting that collecting ducts provide a specific microenvironment for HSCs. In order to identify niche factors in collecting ducts, we performed microarray analysis in collecting ducts isolated from the Tg(jam1a:EGFP) zebrafish kidney. Collecting ducts were isolated from Tg(jam1a:EGFP) zebrafish under a fluorescent microscope. To examine the effect of X-ray irradiation on the niche, collecting ducts were isolated from the fish irradiated with 25Gy. The whole kidney tissues were also used for a comparison analysis. Two independent replicates consisting of five zebrafish were prepared for each sample.

Project description:Kidneys are essential for acid-base homeostasis, especially when organisms cope with changes in acid or base dietary intake. Because collecting ducts constitute the final site for regulating urine acid-base balance, we undertook to identify the gene network involved in acid-base transport and regulation in the mouse outer medullary collecting duct (OMCD). For this purpose, we combined kidney functional studies and quantitative analysis of gene expression in OMCDs, by transcriptome and candidate gene approaches, during metabolic acidosis. Furthermore, to better delineate the set of genes concerned with acid-base disturbance, the OMCD transcriptome of acidotic mice was both compared to that of normal mice and mice undergoing an adaptative response through potassium depletion. Metabolic acidosis, achieved through a NH4Cl-supplemented diet for 3 days, not only induced acid secretion, but also stimulated the aldosterone and vasopressin systems and triggered cell proliferation. Accordingly, metabolic acidosis increased the expression of genes involved in acid-base transport, sodium transport, water transport and cell proliferation. In particular, more than 25 transcripts encoding proteins involved in urine acidification (subunits of H-ATPase, kidney anion exchanger, chloride channel Clcka, carbonic anhydrase 2, aldolase) were co-regulated during acidosis. We propose that these trancripts cooperating to a same function and co-regulated during acidosis constitute a functional regulon.

Keywords: SAGE; Kidney collecting duct; Mouse; Metabolic acidosis; V-ATPase Approximately 650 OMCDs were microdissected, as previously described from collagenase-treated kidneys of 6 mice fed the NH4Cl-supplemented diet for 3 days. 20960 tags were sequenced in the acidosis SAGE library. After withdrawing duplicate ditags and linker sequences, the 19146 tags remaining corresponded to 8847 different tags.This acidosis library is similar in size and diversity to the normal mouse OMCD libraries previously generated (GEO accession number : GSM23478). The tag abundance in the two library was compared and discussed.

Project description:Kidney formation requires the coordinated growth of multiple cell types including the collecting ducts, nephrons, vasculature and interstitium. We show that during development, the interstitium is a highly heterogeneous, patterned population of cells that occupies distinct positions correlated to the adjacent parenchyma. Our analysis indicates that the heterogeneity is not a mere reflection of different stages in a linear developmental trajectory but instead represents several novel differentiated cell states. Further, we find that beta-catenin has a cell autonomous role in the development of a medullary subset of the interstitium and that this non-autonomously affects the development of the adjacent epithelia.

Project description:Notch signaling deficient kidney collecting ducts may serve as a useful resource to identify principal cell lineage and intercalated lineage specific factors since they develop a reduced number of principal cells and an increased number of intercalated cells compared with wild type kidney collecting ducts. We compared RNA from three E18.5 mouse kidneys per group: HoxB7Cre;RBPJf/-;Rosa+/Eyfp (Notch signaling deficient; mutant) versus RBPJf/f;Rosa+/Eyfp (wild type).

Project description:A comprehensive cellular anatomy of normal human kidney is crucial to address the cellular origins of renal disease and renal cancer. Some kidney diseases may be cell type-specific, especially renal tubular cells. To investigate the classification and transcriptomic information of human kidney, we performed a method to obtain single-cell suspension of kidney rapidly, and conducted single-cell RNA sequencing (scRNA-seq). We present scRNA-seq data of 23,366 high quality cells from human kidneys of 3 donors. In this dataset, we show 10 clusters of normal human renal cells. Due to the high quality of single cell transcriptomic information, proximal tubule (PT) cells were classified into 3 subtypes and collecting ducts cells into 2 subtypes. Collectively, our data will provide a reliable reference for the studies of renal cell biology and kidney diseases.

Project description:Diabetic kidney disease is a major complication in diabetes mellitus, and the most common reason for end-stage renal disease. Patients suffering from diabetes mellitus encounter glomerular damage by basement membrane thickening, and develop albuminuria. Subsequently, albuminuria can deteriorate the tubular function and impair the renal outcome. The impact of diabetic stress conditions on the metabolome was investigated by untargeted gas chromatography-mass spectrometry (GC-MS) analyses. The results were validated by qPCR analyses. In total, four cell lines were tested, representing the glomerulus, proximal nephron tubule, and collecting duct. Both murine and human cell lines were used. In podocytes, proximal tubular and collecting duct cells, high glucose concentrations led to global metabolic alterations in amino acid metabolism and the polyol pathway. Albumin overload led to the further activation of the latter pathway in human proximal tubular cells. In the proximal tubular cells, aldo-keto reductase was concordantly increased by glucose, and partially increased by albumin overload. Here, the combinatorial impact of two stressful agents in diabetes on the metabolome of kidney cells was investigated, revealing effects of glucose and albumin on polyol metabolism in human proximal tubular cells. This study shows the importance of including highly concentrated albumin in in vitro studies for mimicking diabetic kidney disease.

Project description:Lithium treatment is commonly used to treat bipolar disorder. However, this treatment disrupts kidney fuctionality. We used microdissected cortical collecting ducts to study proteomics and ultimately discover what changes occur in protein expression after 72-hr lithium treatment.
